You could put a large cable tie round the top tube between the taco and the seat tube with a small cable tie throughit and round the cable to pull it further back and more central while it passes throught he linkage if you don't want to re cable the shifter.

By the way - you can run the rear brake line to the right side of the headtube and the rear mech line to the left of the headtube and all the way down the Downtube, then have them cross over in front of the shock on DW Turners. That's what many who use right-hand front braking do, as it enables smoother arcs for the cables.

I saw a post on MTBR where DT also recommended that as a good thing. Although if you have a coil as Toons does you may want to check that the cable/hoses have enough clearance. It's certainly no problem with air shocks.
